`To all whom it may concern.'

Bo it known that l. (imam: W. citizen of tho vUnited Stairs, rrshling at Staunton, Virginia, havo` invrntrtl (fortuin new and ilfieful iin irovcmonts in 'lahnlaiing Mechanism for Typo-llritcrs, of which the following is a Specification.

My invontion rlatos to lahnlaling xno h mnifim for typewriters and onoy oiicct is to provide a series of Stops one for cac i Column which l) omzetting willi thtl lnlinlaiin r will cna l@ the carriage to be instant mi, any desired sition for priniintli7 i proper position in that .column the the desimd denomination. i ami also to rovide u tahulaior which by moving an ingek to the proper position on a scale will sot the paper carriage, for printing the number accurately in posiions according to its denomination.

In carrying ont Duim-n',

stop y Soi n the ignro of my invtntion l provide a hand operated device such as a lever at or adjacent the key hoard and bv moving this in relation to a suitable scalo or dial the paper carriag'can he not in iliforontzposition accordingr to the, marks on thcsaid scalo. li have sought lss to provide antomaticall operating means for taking np tho Shoal( incidentI to releasing the carriage to he inipeled byNits s ring freely and than arrosting it suddenly, said moans bring', thrown into operation auiornatioally when tlv.x tainillnting iB to lo@l dono but living normally inactive as against the fort-.o of thc carriage prin The invention consists in ih(` fuatnrvs and oomb'mation and nrrangcmrni of )artshoriz. inaftr doscril'iud and partivnlariy pointed 'out in tho ciaims.

ii order to Het the piiper carriage with its stop u inst the appropriate tiibuliiting stop on t io segment it is necessary to disengiige the carriage from its campement mechanism to allow it free movementl towiird the left under the nction of its spring. 'Iliis disengnging notion takes pince simiiltiiiicmisly with the swinging movement of tho tnliulutiii v segment. and from the suine set of connections. 'Iliis mechanism consists of an. tirni 26 fixed oii theiihnft. 27 to which iilso is fixed iinother iirin 28 reaching down within range of an arm 29 fixed on the nlnift 18. This iirin hiui ii portion or riin 30 eoncentric with itx iixis of rotation and tho end of the nrin 28 is curved to correspond.
